Dunno what ESC is as an interrupt keystroke; unlike ^C (which is often,
although not always, the "intr" character) and ^Z (which is usually the
"susp" character), ESC isn't normally an interrupt keystroke.  It may be
used as a "secondary end-of-line" character by some shells, such as
those that support filename completion, but that's not an interrupt
keystroke.

*And* the ones assigned to "quit", "swtch" - *and* "susp", if your system
has an S5-flavored tty driver and job control.
